Modeling and Evaluation in an Interworking of WLAN and WiMAX Network

The complementary characteristics of Worldwide Interoperability for Microwave Access (WiMAX) and IEEE 802.11 Wireless Local Area Network (WLAN) networks make them attractive for integration to offer the best of both technologies. However, in order to make the integration effective, the in-depth mobility study by simulation is necessary. This paper addresses the simulation models for mobility management procedures in an interworking of WiMAX and WLAN network for the various integration scenarios. The mobile multihomed node models of WiMAX and WLAN interfaces are developed and simulated in various traffic environments and network integration topologies including group mobility and MANET. The simulation results show that the developed models are useful for mobility studies in various integration wireless networks.
